CABf-COUPLING.

.declare the following to be a full, clear, and

exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention relates to car couplers.

The object of the invention is to provide a simple and efficient coupler whose operation and construction will be such that a brakeman or other attendant operating the same could disconnect or connect the cars without having to step in between them,

. thereby endangering his life.

With this and other objects. in view, the invention consists of certain novel features of-constructin, combination and varrangement of parts, as will be more 'fully described and particularly pointed out in the appended claims.

In the drawings: Figure 1 represents a top plan view; Fig. 2 is a vertical longitudinal section taken on an irregular line through Fig. 1. Fig. 3 is a horizontal section on the line 3-3 of Fig. 2. Fig. 4L is a detail transverse section'on the line 4 4 or' Fig. 1. Fig. 5 is a detail perspective of the disengaging rod; Fig. 6 is a detail perspective of the locking rods.

Referring more especially to the drawings, 1 represents the coupler head and shank by which the head is connected to the drawbar. The head is hollowed out, as is usual on the front side, as shown at 3, to provide a socket for the jaw on the opposite coupling head. Communicating with this socket on each head is a recess 4 which is adapted to receive the actuating tongue 5 of the locking jaw 6, which in this instance is pivoted between the extending lugs 7 projecting from the head and one side of the socket 3.

When the jaw is in locking position, the tongue 5 is seated in the recess 4 so as to be completely hid therein and be adapted to be engaged by a locking rod to be hereinafter described.

On the upper side of the head there is provided a recess or well 8 in which is seated the connecting head 9 of the locking and re- Specilication of Letters atent.

taining pins or rods 10 and 11. The pin 11.

passes entirely through the head and is locked from removal upon the. underside of the head by a Cotter pin, so as to prevent the complete withdrawal of the locking pin 10, which passes through alined apertures 13 and overlies the curved end of the locking tongue lWhile this pin is adapted to be withdrawn'sutliciently to free the tongue 5, the cotte-r pin 12 on the retaining rod 11` prevents its complete withdrawal, and maintains the said rod in position to be dropped int-Q locking position when necessary.

Pro'cctino through an a Jerture 14 is a disengaging rod 15 which has formed on its body a cam 16, which is formed by cutting away, as at 17. vl/*hen the locking pin is in depressed position, this cut-away por tion permits the tongue to be fully swung within the socket 4e, but if the locking pin is raised when the locking pin 10 is out of engagement with the tongue the cam 16 engages the rear side thereof and forces the tongue outwardly, so that a positive disconnection of the jaws on the couplers is insured.

Connected at one end to the head 9 by a flexible chain 18 is a connecting link 19,

whose opposite end is connected in a similar manner by a chain 20 to the disengaging pin 15. This link is provided with a slot 21 extending diagonally across its body and having one end thereof terminating adjacent the center of the link, where it has passed through it, the connecting clevis for the operating chain 22. This chain is shown suspended in the air, but it will be clearly understood that it may be operated in any suitable manner to raise the head 9 and the disengaging 'pin-'15. A

When a pull is exerted upon the operating member or chain 22, the link 19 with its locking and retaining pins 10 and 11 Ais raised until the Cotter in 12 engages the underside of the coupling head. During this movement the rod 15 remains practically stationary and the connection between the operating member and the link 19 slides in the slot 21 until the rods or pins 10 and 11 reach their limit of upward movement, at which time, if the pull is maintained upon the operating member 2Q, the rod 15 will be raised to disengage'the tongue 5 from its recess 2l. y`When the pull upon the member 22 is slacltened, the rod 15 will drop into LLP vthe construction and operation o place, as shown in Fig. 2, and-the pin will subsequently drop into place, with the pin 10 in engagement With the tongue Connected to one side of the head by n staple or other device 23 is n short chain 24 having secured to its end e bool-z 25 adapted to engage en eyelet on the side of the adjoining or co-ecting-conpler. A. similer eye is shown at 25 on the opposite side of the head 1, which is adapted to receive the hook -o the opposite coupler. These parte are provided should the tongue or a jew of the coupler become broken.

From the foregoing description, teken in connection wit-h'tbe eccom-panyin drawings,

fthe invention Will be readily understood without requiring a more `extended explenn.tio1'1 Various changes lin the form, proportion end the minor details of construction may be resorted to Without departing from the principle or sacrificing any of tbe advantages of this invention es deined in the appended claims.

Having thus described our invention, what We claim as new end desire to secure by Letters-Patent, is:

1. ln e 'car coupler, ebend, e jew pivoted @como to the head, a locking'pin for the jaw, a jaw disengaging member, an operating member, iexible members connected to the pin and disengnging member., and a connecting link between the flexible member and the operetin` members which causes the operation of tbe pin and disengaging member in sequence.

2. ln e cnr coupler, a heed, a, jaw pivoted to the hearba locking pin for the jaw, e jew disengnging member, an operating member, flexible members connected to' the pin and disengaging member, and a slotted connecting link having .the flexible member carried by the disengaging member connected to one end and the Hexible member carried by the pin connected in seid slot,

and e connection between the operating;A

member which engages and is slidebly mounted in the slot.

1n testimony whereof We have hereunto set our hands in presence of two subscribing Witnesses.
